Tissues
Epithelia, connective, muscle and nervous
Natalie Crowder
There are four main tissue types within the human body named the Epithelial, connective, muscle and nervous tissue.
Epithelial tissue
The Epithelial tissue is the lining of the internal and external surface of the body cavities that include the tubes that carries the secretions away from the glands. The composed compound epithelial tissue is made up of several layers, and the simple epithelial tissue is a single layer cells. The bottom layers of cells are connected to the membranes for support.
Each part of the membrane cells is secreted by the epithelia, the nerve part of the tissue supplies are with oxygen and nutrients from the deeper tissue, the tissues that are supplied with oxygen are called diffusion, this is where the passage of molecules from a high concentration to a low concentration.
For example,
Once the tissues surface and exposed there responsibility is to repair and grow new cells whilst we sleep.
Single Epithelia
These cells might be called Squamous, cuboidal, columnar or ciliated, the squamous cell is described, as flat thin cells are located in the tissue that forms the surface of the skin. The cell is a necuals is inside the surface of the cell structure that is a white lining and only has one layer of the surface and situated in the lung of the alveoli, blood capillaries, bowman’s capsule of neurons for example bowman’s capsule collect the filter entering the tubes when all glucose are reabsorbed into the blood of the capillaries, the rest of the cells travel the tubes water and salt when the body needs it and the whole process as urine. These are found in the kidney, sweat duct, glands such as thyroid and breast tissue and may be responsible for causing kidney disease.
Columnar epithelia
Simple columnar epithelia tissues are cells that are found throughout the body system which include the digestive system and reproductive system. The cells also main purposes...
